It was bought for £50m by the National Gallery and National Galleries of Scotland with contributions from the Scottish Government, National Heritage Memorial Fund, The Monument Trust, The Art Fund and the public.

Vanessa Trevelyan, head of Norfolk Museums and Archaeology Service, said: "Titian was renowned as a painter of sexy mythology pictures during his lifetime.

"Ever since Diana and Actaeon came to Britain in 1798, it has been a powerful source of inspiration for artists.

"The painting was bought by the Duke of Bridgewater, whose descendants made it available to the public and sold it to the nation in 2008.

"It is a real privilege to be invited to show this important work, and we are enormously grateful to the National Gallery for offering us this unique opportunity."

Widely considered to be one of the most important paintings of the Italian Renaissance now in public ownership in this country,Diana and Actaeonis based on the poem Metamorphoses by the Roman poet Ovid.

Exhibition officer Heather Guthrie said: "In Victorian times, paintings were shown in public as a real spectacle and people would queue around the block to go and see a painting by a particularly well known artist as it was the best picture show in town.

"I don't know if we'll have the queues around the block, but it's a unique opportunity to see this painting by one of the world's great artists and to really try to come to an understanding as to what makes this such a fantastic painting."

On Friday, the sister painting to Diana and Actaeon -Diana and Callisto- was purchased for the nation after a £45m ($71.7m) deal was agreed with owner the Duke of Sutherland.

The "supremely important" oil painting was bought with the help of £25m ($39.9m) from the National Gallery after a lengthy fundraising campaign.

Titian's Diana and Actaeon can be seen at Norwich Castle Museum until 15 April.
